Introduction

I can't take credit for much of the work here -- I adapted it from this blog post: https://tech.willhaben.at/mongodb-incremental-backups-dff4c8f54d58

My main contribution was to make it a little easier to use with docker as well as numerous little cleanup tasks. I also made it gzip the oplog backups and added support for SSL connections

Note that I havne't yet tested the point in time restore script; it likely needs work, particularly to make things work with the gzipped oplog files

Simple Hand Gesture Recognition Code - Hand tracking - Mediapipe

Goal of this gist is to recognize ONE, TWO, TREE, FOUR, FIVE, SIX, YEAH, ROCK, SPIDERMAN and OK. We use the LANDMARKS output of the LandmarkLetterboxRemovalCalculator. This output is a landmark list that contains 21 landmark. In the 02-landmarks.jpg picture below you can see the index of each landmark. Each landmark have x, y and z values. But only x, y values are sufficient for our Goal. If you dont want to copy/paste each the code on this gist, you can clone my forked version of mediapipe here: https://github.com/TheJLifeX/mediapipe. I have already commited all code in that repository.

We have five finger states.

Building TensorFlow 1.3.0-rc1 for Raspberry Pi/Ubuntu 16.04: a Step-By-Step Guide

Here you'll learn how to build Tensorflow for the raspberry pi 3 with either the Python API or as a standalone shared library which can be interfaced from the C++ API and eventually as a library which can be used in other languages.

For the C++ library this tutorial will show you how extract tensorflow library and headers to use in any environment you want.

(This tutorial couldn't be possible without the help of the people from the References section)
